Sector antenna Ubiquiti AMO-3G12 12 dBi 3.4-3.7 GHz

The Ubiquiti AMO-3G12 sector antenna provides 12 dBi gain for the 3.4–3.7 GHz band and uses dual polarization to deliver reliable coverage. Designed to pair with RocketM radios (sold separately), it offers a focused horizontal beam for sector deployments and a compact form factor suitable for outdoor wireless basestations and point-to-multipoint links.

Advantages

The AMO-3G12 combines carrier-class performance and dual-polarity MIMO to improve link robustness and capacity. Its beam characteristics and compatibility with airMAX technology enable efficient use of airtime via TDMA scheduling, reducing collisions and improving latency and throughput. The antenna supports intelligent QoS prioritization for voice and video and is sized for straightforward mounting in sector and basestation installations.

Suitable for

• Sector basestations in point-to-multipoint wireless networks
• Outdoor deployments in the 3.4–3.7 GHz frequency band
• High-capacity links requiring dual-polarity MIMO

How to use

Mount the AMO-3G12 on an appropriate mast or sector bracket aligned to the desired coverage sector. Connect the antenna to a compatible RocketM radio or another suitable outdoor radio using the correct coaxial cable and connectors. Configure the radio to operate in the 3.4–3.7 GHz band and, if available, enable airMAX/TDMA features and QoS settings to optimize link performance. Ensure mechanical fittings are tightened and weatherproofed according to site standards.

Recommendations

Install at a clear height with unobstructed line of sight to client devices where possible; verify local regulatory frequency and power limits for operation in the 3.4–3.7 GHz band. Use surge protection and grounding for outdoor deployments.
